Sometimes you can just use common sense to figure out trends.
USAToday/Fandango has "A Christmas Story" ranked 7th among millennial's, losing to, you guessed it, movies like "Elf" and "Home Alone".
According to YouGov below: Christmas Story has dropped in popularity, and that's not even factoring in what Gen Z thinks of it. All of the other older movies have dropped in popularity as well, Miracle, White Christmas, IAWL. Meanwhile, movies like Elf and Home Alone are far more popular with Millennial's than A Christmas story.
It's so weird isn't it, that new generations prefer movies that not only 1. came out when they were born, and 2. take place during a time they are familiar with?
